Abstract
Abstract An electrode for use in low intensity direct current therapy of skin lesions and the like. The electrode contains silver from which silver ions are carried to the treatment site under the influence of direct current to provide a germicidal action at the lesion. The electrode may have a porous support structure and some of the silver may be chlorided. The electrode is maintaned in substantially direct contact with the treatment site while being saturated with an electrolyte similar to tissue fluids.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
77 words
A method of treating skin ulcers, lacerations, wounds and the like, wherein said method comprises the steps of: a. maintaining a first side of a silver-silver choride bearing porous electrode in substantially direct contact with the skin; b. providing an electrolyte solution on the second side of said electrode so that said electrolyte is carried through the porous electrode; and c. maintaining a positive direct current flow through said electrode so that said electrode is an anode.
Claim 2
Independent Claim
77 words
A method of treating skin ulcers, lacerations, wounds and the like, wherein said method comprises the steps of: a. maintaining a first side of a silver-silver choride bearing porous electrode in substantially direct contact with the skin; b. providing an electrolyte solution on the second side of said electrode so that said electrolyte is carried through the porous electrode; and c. maintaining a positive direct current flow through said electrode so that said electrode is an anode.
Claim 3
Dependent Claim
24 words
A method as set forth in claim 1, wherein said current flow is in the approximate range of one hundred nanoamps to 50 microamps.
